ixgbe: fix build without builk alloc

If RTE_LIBRTE_IXGBE_RX_ALLOW_BULK_ALLOC is disabled in the config file,
RTE_PMD_IXGBE_RX_MAX_BURST macro and ixgbe_recv_pkts_bulk_alloc function
are not declared, and some parts of the ixgbe code were still trying to
use them.

Fixes: 01fa1d6215fa ("ixgbe: unify Rx setup")
